CWE-639 Authorization Bypass Through User-Controlled Key Primary CWE-639 Authorization Bypass Through User-Controlled Key

CWE-639 — Authorization Bypass Through User-Controlled Key: The system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data.

[Architecture and Design] For each and every data access, ensure that the user has sufficient privilege to access the record that is being requested.
[Architecture and Design, Implementation] Make sure that the key that is used in the lookup of a specific user's record is not controllable externally by the user or that any tampering can be detected.
